[0047] The temporary construction road ecological drainage device may also include any other suitable components. In a specific embodiment of this utility model, the temporary construction road ecological drainage device also includes organic fertilizer, which is mixed in the planting soil layer 5.

[0048] Before using the recycled plastic board 2, some preparatory work needs to be done. Specifically, clean the drainage ditch 1 on the side of the road, compact the bottom of the ditch and make it form a slope of, for example, 1%-2%. Fix (e.g., by plugging or pre-embedding) the left front fixing block 11 and the right front fixing block 13 to the front side wall of the drainage ditch 1, and fix (e.g., by plugging or pre-embedding) the left rear fixing block 12 and the right rear fixing block 14 to the rear side wall of the drainage ditch 1. Then, lay the recycled plastic board 2 in the vertical groove 8 of the recycled plastic post 3 from bottom to top. Set up a coarse sand layer 6 and a planting soil layer 5. The coarse sand is used for rapid water drainage and to prevent soil erosion. The planting soil can be mixed with 5% organic fertilizer (such as well-rotted straw) to improve water retention and the survival rate of grass seeds. Sow grass seeds (such as ryegrass, tall fescue, or bermudagrass) evenly in the planting soil layer 5, and then lay a non-woven fabric layer 4 on top of the planting soil layer 5 to prevent erosion that could cause the grass seeds to detach from the seedlings later. Spray water 1-2 times a day (for 7-10 days). Because the non-woven fabric layer 4 has vertically arranged through holes 9, the grass seedlings can grow... The position can be manually adjusted over time to allow the grass seedlings to grow through the through-hole 9 until the seedlings reach a height of 5cm or more, forming a stable vegetation layer. The recycled plastic board 2 is placed in the drainage ditch 1 and placed on the left front fixing block 11, left rear fixing block 12, right front fixing block 13, and right rear fixing block 14. The recycled plastic board 2 is then fixed to the left front fixing block 11, left rear fixing block 12, right front fixing block 13, and right rear fixing block 14 respectively using the left front fixing bolt 15, left rear fixing bolt 16, right front fixing bolt 17, and right rear fixing bolt 18 to complete the installation. When rainwater flows through the recycled plastic column 3, the vegetation layer intercepts large particles of mud and sand, the coarse sand layer 6 adsorbs fine particulate pollutants (such as suspended solids, heavy metals, etc.), and the grass roots secrete organic acids to decompose some of the oil and other organic pollutants. After being treated layer by layer, the rainwater is finally discharged into the drainage ditch 1 through the drain hole 10, thus completing the ecological filtration and drainage of rainwater. The filtered rainwater can also be used for vehicle washing or concrete curing, forming a closed-loop system and saving resources. In addition, the vegetation layer can slow down the water flow and reduce erosion of the ditch bottom, and multiple recycled plastic columns can disperse the water flow pressure and prevent local water accumulation.

[0049] When the water flow is large, the water that is above the top of the drain pipe 7 can flow into the drain ditch 1 through the drain pipe 7, thus preventing water from overflowing the drain ditch 1.

[0050] Check vegetation coverage monthly, replant or remove weeds in localized areas to ensure the efficiency of ecological filtration. After the project is completed, remove the recycled plastic boards for reuse, and transplant the grass seedlings to other green areas for recycling to avoid waste.

[0051] This utility model features modular installation, allowing two people to complete the laying of a 100m drainage ditch 1 in one day, with low cost. Recycled plastic boards 2, recycled plastic pillars 3, and grass seedlings can all be reused, making it more environmentally friendly.

[0052] The applicable scenarios for this utility model are temporary roads (such as building construction sites and water conservancy project access roads) with a construction period of ≤6 months, and sandy or clay areas with moderate rainfall intensity (daily rainfall ≤50mm).

[0053] Therefore, the present invention has the following beneficial effects:

[0054] 1. Using this utility model, grass seedlings are easily planted inside the recycled plastic column for ecological filtration. Large particles of mud and sand are intercepted by the vegetation layer, and fine particulate pollutants (such as suspended solids and heavy metals) are adsorbed by the coarse sand layer. The grass roots secrete organic acids to decompose some organic pollutants such as oil. After being treated in layers, the rainwater is finally discharged into the drainage ditch through the drainage holes, thus completing the ecological filtration and drainage of rainwater. The filtered rainwater can also be used for vehicle washing or concrete curing, forming a closed-loop system and saving resources.

[0055] 2. By using this utility model, the vegetation layer can slow down the water flow speed and reduce the scouring of the ditch bottom. Multiple recycled plastic columns can disperse the water flow pressure and avoid local water accumulation. Rainwater protruding from the top of the drain pipe can be discharged into the drainage ditch in a timely manner to prevent water from overflowing the drainage ditch.

[0056] 3. This utility model uses recycled plastic boards and recycled plastic columns. The recycled plastic boards can be detached and installed in the drainage ditch, which is environmentally friendly and reusable. The grass seedlings can be transplanted to other green areas for recycling, avoiding waste.

[0057] In summary, the ecological drainage device for temporary construction roads of this utility model can effectively filter rainwater. The filtered rainwater can be used for vehicle washing or concrete curing to save resources. It can also reduce scouring of the ditch bottom, avoid local water accumulation, ensure smooth drainage, is environmentally friendly and reusable, has an ingenious design, simple structure, is easy to manufacture, has low manufacturing cost, and is suitable for large-scale promotion and application.

[0058] Therefore, it is evident that the objective of this utility model has been fully and effectively achieved. The function and structural principles of this utility model have been demonstrated and explained in the embodiments. Without departing from the stated principles, any modifications can be made to the implementation methods. Therefore, this utility model includes all modified embodiments based on the spirit and scope of the claims.
